DEVICE FOR SMOKELESSLY HEATING INSECT-POWDER,

SPECIFICATION forming part of Letters lE'ate nt No. 692,075, datedJanuary 28, 1902.

Application filed July 11, 1901. Serial No. 67,856. (No model.)

To all whom it may concern.-

Be it known that I, JOHN C. SEARLE, a citizen of the United States, anda resident of Hilea Kau, Territory of Hawaii, have invented a new andImproved Device for Smokelessly Heating Insect-Powder, of which thefollowing is afull, clear, and exact description.

The purpose of the invention is to provide a device so constructed thatit may be applied to a lamp-chimney, gas-globe, electric light, or thelike, which device is adapted to contain a powder the fumes whereof havea killing effect upon such insects as mosquitos, and to so apply thedevice to a lamp or its equivalent that the powder will be roasted andnot consumed by fire, thereby obtaining fumes obnoxious to insects andyet free from the accompanying smoke consequent upon firing or burningthe powder.

The invention consists in the novel construction and combination of theseveral parts, as willbehereinafter fully set forth, and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical section through the upper portion of alamp-chimney and a vertical section through the improved device appliedthereto. Fig. 2 is a plan view of the improved device. Fig. 3 is apartial vertical section through the device, illustrating the manner inwhich the device may be adjusted to or from thetop of a chimney. Fig. 4is a side elevation of an electric lamp and a slightly-modified form ofthe device applied thereto, and Fig. 5 is a plan view of the deviceshown in Fig. 4 and a horizontal section through the electric lamp.

Under the form of construction shown in Figs. 1, 2, and 3 a tray Aconstitutes the body of the device. This tray is more or less dished,being concaved at its upper and convexed at its lower surface. The saidtray is preferably circular in form and is of such dimensions that itwill extend beyond the sides of the lamp-chimney O at the top, to whichit may be applied. This tray is constructed of wire-gauze or may be madeof perforated metal, if desired, and said tray is provided with a seriesof legs B. These legs are constructed of a pliable metal, ordinarilyfrom strips of soft metal, and each leg comprises a main outer section10 and an inner shorter section 11, the shorter section ll of a leghavinga foot 12 at its lower end. Where the two sections of a leg arebrought together or where the material of the leg is bent upon itself, ahead 13 is formed, and said head is usually given an upward and outwarddirection or inclination. The legs 13 are attached to the tray A,usually by producing parallel slots 14:, in the tray near its margin, asis shown in Fig. 2,through-which slots the heads of the legs B arepassed.

When the device is to be placed upon a lamp-chimney, ordinarily thefoot-sections 12 of the legs rest upon the top edge of the chimney O, asis shown in Fig. 1, while the longer and outer members 10 of the legextend down at the exterior of the chimney and have bearing against suchsurface. The powder E is placed, in suitable quantities, upon the uppersurface of the tray, and the heat from the flame of the lamp will slowlyroast the powder, thus causing it to give off fumes. By roasting thepowder instead of consuming it by a flame all of the properties of thepowder will be retained and rendered of service, while the fumes areunaccompanied by obnoxious smoke so' common to devices employed forsimilar purposes.

Should the tray be too far above the upper portion of the chimney, thedistance between the top of the chimney and the tray may be regulated bybending inward the shorter section 11 of the leg, so that the saidsections will engage with the inner face of the chim hey at the top, asis shown in Fig. 3.

In order that the device may be readily ap plied to a chimney or removedtherefrom, a

handle F is employed, which handle consists usually of a central section15 and legs 16, which extend two in number from the ends of the centralsection and terminate at their lower ends in hooks 17,passed upwardthrough the tray A, near its margin.

In Figs.4 and 5 I have illustrated the adaptation of the device to anelectric lamp G. In such adaptation a circular framelA is employed, madein two sections a and a, connected by a hinge 18 at one end, the otherends of the sections being adapted to be closed around the neck of theglobe of the electric lamp by a fastening device (6 of any approveddescription. This frame A is provided with a perforated or reticulatedbottom 19 and with corresponding sides 20, and the powder is placedbetween the members of the frame, resting on the bottom and against thesides thereof.

When the device is to be applied to a gasglobe, it is simply necessaryto carry the legs B to a horizontal position, so that the longer members10 of the legs may rest upon the upper edge of the gas-globe.

It will be observed that when a device of this description is employed aroom may he fumigated and insects destroyed without inconvenience to theoccupants of said room, since the operation of roasting the powderrenders it smokeless.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A device for smokelessly heating insectpowder,comprising a web for holding the powder, said web being substantiallycircular in outline and composed of wire meshes fine enough to preventthe passage of said powder through the same, and means for holding saidweb in form and for securing the same upon a lamp-fixture.

2. A device for smokelessly treating insect powder, which consists of areticulated tray, legs attached to the said tray, which legs are pliableand are in two sections, a long and a short section, the said legs beingadapted for engagement with the chimney of a lamp or the globe of a gasor electric fixture, the legs being adjustable to bring the tray closerto or carry it farther away from the globe or chimney as required.

3. A device for smokelessly treating powder, which consists of areticulated tray, having legs of a pliable material, each of the saidlegs comprising two members, a long and a short member, and a handleconnected with the upper portion of the tray, the legs extendingdownward from said tray, for the purposes set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN C. SEARLE.
